Tamoxifen	3.55	*	4.61 × 10−5
White	1.94	14.76	6.17 × 10−8
Other	2.04	*	1.18 × 10−2
LVI negative	3.86	*	4.71 × 10−6

ER−/PR−/HER2− represents “triple-negative patients”. 

P values are based on log-rank tests on the stratified Kaplan-Meier curves. 

^*Denotes that less than half the at-risk patients had an event, resulting in no estimate of median PFS.
